We're dividing 42260397 by 771 
The aim is to understand the frequency of 771 in 42260397.

Step 1:
4 divided by 771 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 771

Step 2:
When dividing 42 by 771, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Append the next digit (2) from the dividend to 42 and continue with: 422 / 771

Going ahead to step 3:
771 can be fit into 422 0 times, resulting in a remainder of 422.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 422 leaves us with 422.
Take the next digit (6) from the dividend and append it to 422, then repeat: 4226 / 771

On to step 4:
771 can be fit into 4226 5 times, resulting in a remainder of 371.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 3855 from 4226 and we're left with 371.
Bring next digit (0) of the dividend behind the 371 and repeat the process: 3710 / 771

Step 5:
The number 771 fits into 3710 4 times, leaving a remainder of 626.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
If we subtract 3084 from 3710, we get 626.
Grab the next digit (3) from the dividend, add it to 626, then carry on: 6263 / 771

Let's proceed to step 6:
When dividing 6263 by 771, we get 8 with a remainder of 95.
Use 8 as the next digit of our solution. 
Result so far: 548.0
Subtract 6168 from 6263 to get 95.
Append the next digit (9) from the dividend to 95 and continue with: 959 / 771

On to step 7:
959 divided by 771 is 1 with a remainder of 188.
Write down 1 as next digit of the result. 
Result so far: 5481.0
Deduct 771 from 959 and we're left with 188.
Include the next digit (7) from the dividend after 188, then repeat: 1887 / 771

Going ahead to step 8:
If we divide 1887 by 771, we get 2 and a remainder of 345.
Write down 2 as next digit of the result. 
Result so far: 54812.0
The remainder is 345 after subtracting 1542 from 1887.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Let's proceed to step 9:
The number 771 fits into 3450 4 times, leaving a remainder of 366.
Record the quotient 4 as the next digit in the result. 
Result so far: 54812.4
Subtract 3084 from 3450 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 10:
771 goes into 3660 4 times with a remainder of 576.
The next digit of our result is 4. 
Result so far: 54812.44
Subtracting 3084 from 3660 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

The quotient of the division is 54812.44, and the remainder is 0.576.
